--- Comment #1 from Frédéric Wang (:fredw) <fred.wang at free.fr> ---
After more analysis, this is a more accurate description of the behavior I see:

* For the options that are not in the setters[] array then WebPreferences::setEnabledForFeature is never called. This includes the obsolete UI items "CSS display: contents", "Remove Legacy WebRTC API" and "Viewport Fit". Note that I was testing with WEBGPU disabled in comment 0 so "WebGPUEnabled" was not in the setters[] array.

* If you enable "Constant Properties", then WebPreferences::setEnabledForFeature is *not* called for "ConstantPropertiesEnabled". If you disable "Constant Properties" then WebPreferences::setEnabledForFeature is called.

* For other properties, this is the other way around: WebPreferences::setEnabledForFeature is called when the option is enabled but *not* when the option is disabled. This includes the case of "AsyncFrameScrollingEnabled" mentioned in comment 0.

* If "Constant Properties" was disabled when you modified the value of another option then WebPreferences::setEnabledForFeature is called for "ConstantPropertiesEnabled" in addition to any other calls mentioned above.
